+doh - forgot to add example of what kind of mode of operation I am talking about
+
+<details>
+<summary>Here is the script</summary>

+```shell
+#!/bin/bash
+set -ex
+
+cd \"$(mktemp -d ${TMPDIR:-/tmp}/dl-XXXXXXX)\"
+
+mkdir orig
+( cd orig; git init; git annex init; echo 123 > 123; git annex add 123; git commit -m 123 123; )

+cd ephemeral

+# making it ephemeral
+ln -s ../../orig/.git/annex .git/annex

+)
+

+</details>
+
+running which at the end produces
+
+```
